Albanese — who served in the City Council when de Blasio was David Dinkins’ liaison to the Council — told radio host Curtis Sliwa on Friday how he, his wife, Lorraine, and dozens of other guests sweltered under a hot sun in Prospect Park that day in 1994, waiting for the groom to appear.

“There was no shade. My wife was furious, and kept nudging me,” Albanese said. “She almost got me to leave.”

De Blasio, who was born Warren Wilhelm Jr., had two aunts from his mother’s side sitting right behind the Albaneses, and they were upset, too.

In Italian — thinking no one could understand their conversation — one said to the other, as translated by Albanese: “Bill was a jerk as a kid, and he continues to be a jerk today.”

Albanese, who emigrated from Calabria at age 8, is fluent in Italian and understood completely.
